Engine Performance problem
1985 Lincoln Continental V8 Two Wheel Drive Automatic 67000M miles

when i start the car in morning it starts ok but when i start driving for a few minuite and begin to reduce speed to stop, the engine start acelerating and speeding up without touching accelerator so i have too apply brakes hard until it stops and then i put it in park and i can tell that idle speed is very high. it is a 5 liter efi engine. let me know as soon as possible and if your solution works i will make a donation for sure .thanks nick

Hi mariano63, Welcome to 2carpros and TY for the donation

Clean out the idle air control valve and also the throttle plate and check the accelerator linkage/cable and also test the throttle position sensor-
